Abstract

An optical device (100) includes a substrate (110), a reflecting stack (120) and optionally, a cap layer (130). The reflecting stack has a first plurality (RH, RL) of optical thin film layers and a second plurality (AR1, AR2) of optical thin film layers. The first plurality of optical thin film layers are carried by the substrate, and are configured and adapted to be highly reflective of light of a first predetermined wavelength incident upon the optical device at a first predetermined angle (RH, RL). The second plurality of optical thin film layers are carried by the substrate and are configured and adapted to be substantially antireflective of light of a second predetermined wavelength incident upon the optical device at a second predetermined angle (AR1, AR2). The second plurality of layers are interposed between individual layers of the first plurality of layers. The cap layer, if provided, is carried by the reflecting stack.
